Hi,
I am trying to run the gwt scaffolding tutorial for 1 week.
I was facing the "RequestFactoryServlet" error message during the launching of the project.
i read your toping for gwt 2.4 user and it fix it. But know when i click on button "get gwt.."
i get this error message :"Error : one or more exceptions caught , see full set in umbrellaException#getCauses".

I'm sorry you're having this problem. That UmbrellaException is a generic error message that is thrown from the GWT apps. Typically, there is an exception in the Server Console view that states the underlying problem. Is there an error being logged to your server Console? If so, please post it here.

Also, it seems the annotation processor will only automatically run if your project is configured to use the Java 6 specification.

I have the same problem using MyEclipse 9.1 for MAC. The Error loops itself and there is no way to break the loop. Every time I click on OK button to dismiss the error, I get the same error again.

Solution to this is posted under Scaffolding GWT2.4 topic
